WebPBKDF2, as implemented by Bitwarden, works by salting your master password with your username and running the resultant value through a one-way hash algorithm (HMAC-SHA-256) to create a fixed-length hash. This value is again salted with your username and hashed a configurable number of times ( KDF iterations ). WebBitwarden has been keeping users on known insecure settings for five years. Mind you, increasing PBKDF2 iterations forever is certainly not the solution. PBKDF2 is a known bad algorithm, it’s way easier to attack than to defend.
